Construction Management System for Mixed Equipment Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction management systems fail to effectively manage construction sites where work machines with and without detecting devices coexist, leading to inefficiencies in data collection and site monitoring.
Innovation Solution
A construction management system equipped with an object detecting unit, shape detecting unit, and information attaching unit, which generates current state information by combining time information with shape information from work machines, enabling communication of construction data between equipped and non-equipped machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all work machines are equipped with detecting devices, then data collection capability is improved, but equipment cost and allocation complexity increase
Solution Approach 1:
The patent introduces a management device as an intermediary that receives detection results from machines with detecting devices and transmits them to machines without detecting devices. This mediator enables information sharing across the construction site, allowing all machines to access detection data regardless of whether they are equipped with sensors, thereby resolving the contradiction between universal data collection and selective equipment deployment
Solution Approach 2:
The management device serves multiple functions: it collects detection results from equipped machines, stores them, transmits them to unequipped machines, and coordinates construction activities. This multi-functional approach allows the system to achieve comprehensive data collection without requiring every machine to have detecting devices, thus reducing overall system complexity while maintaining information availability
2Measurement precision
If detecting devices are installed on all work machines, then construction site monitoring accuracy is improved, but system cost and maintenance burden increase
Solution Approach 1:
The patent merges the detection functions of multiple machines into a centralized management device. Instead of each machine independently performing detection and analysis, the system combines detection efforts at a central location, which then distributes the consolidated information. This merging approach maintains monitoring accuracy while reducing the total number of detecting devices required across the construction site
3Productivity
If real-time shape information is transmitted between machines, then construction coordination is improved, but communication system complexity increases
Solution Approach 1:
The management device acts as a communication intermediary that receives shape information from equipped machines, processes it, and transmits relevant data to unequipped machines. This centralized communication hub simplifies the network architecture compared to direct peer-to-peer communication between all machine pairs, reducing overall system complexity while enabling real-time information sharing for improved construction coordination

AI summary
A construction management system includes: an object detecting unit mounted on a work machine and configured to detect an object in a construction site and output information on the object; a shape detecting unit configured to output shape information indicating a three-dimensional shape of the object by using the information on the object detected by the object detecting unit; an information attaching unit configured to attach, to the shape information, time information indicating a time when the object is detected; and a management device configured to generate current state information on the construction site on the basis of the shape information to which a latest piece of the time information is attached.
